SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 704,014, dated July 8,1902.

Application filed October 21, 1901. Serial No. 79,395. (No model.)

To all whom/it may conccrm Be it known that I, J OHN A. ESPITALLIER, acitizen of the United States, residing at Ohicago, in thecounty of Cookand State of Illinois, have invented certain new and useful Improvementsin Sash-Locks, of which the following is a full, clear, and exactspecification.

My invention relates to sash-locks designed for not only lockingthesashes against rela tive movement, but for also pulling the contiguoussash-rails into alinement and clamping them firmly together, and moreespecially to that class of suchsash-locks in which a keeper is securedto one sash and is engaged by a bolt which is given a combined rotaryand reciprocatory motion by means of a pin and a cam-slot, which causethe bolt to first enter the keeper and then raise it and at the sametime pull it inwardly toward the con-- tiguous sash.

My invention has for its primary object to improve and simplify theconstruction and operation of sash locks of this character whereby thebolt, its operating-handle, the hook for engaging the keeper, and theslot for efiecting the reciprocatory motion of the bolt may be formed inone piece and the pintle or guide upon which the bolt slides may beformed in one piece with its support or base and possess the requisitestrength and rigidity to withstand the great strain to which it issubjected by the bolt, a further object of the invention being to soform the keeper that it will be strong and durable and at the same timecapable of being more or less altered in shape, so asto allow fordiderences in the relative positions of the two sashes when one isentirely up and the other ens tirely down, it being understood that insome instances thetop rail of the bottom sash and the lower rail of thetop sash will be in accurate alinement or flush when in said position,while in other instances one will be more or less below the plane of theother, thus necessitatinga corresponding variation in the relatained,all as fully described with reference to the accompanying drawings, andmore particularly pointed out in the claims.

In the said drawings, Figure 1 is a perspective view of my improvedsash-lock applied to a part of two sashes, showing the lock in the actof locking the sashes together. Fig. 2 is a plan view of the twosash-lock members, showing them unlocked. Fig. 3 is a verticallongitudinalsectional view of the sash lock members applied to the sashand unlocked. Fig. 4 is a side elevation thereof, showing them locked.Fig. 5 is a plan view thereof, showing them entirely locked. Fig. 6 is aplan view of the blank from which the bolt is formed. Fig. 7 is an edgeview of the keeper, illustrating in dotted lines the different formsinto which the keeper may be bent; and Fig. 8 is an end'elevation of thebolt and its supporting-pintle with the base thereof.

1 is the upper rail of the lower sash, and 2 the lower rail of the uppersash. To the upper side of the rail 2 is secured a keeper 3,

and to the rail 1 is secured a base-plate 4;,

upon which is supported the pintle for the sliding rotary bolt beforereferred to.

This

base-plate 4 is formed in one piece of sheet metal, with a standard orsupport 5 rising from one end thereof, and projecting laterally fromthis standard 5 isthe aforesaid pin-- tle 6, which is also formed ofsheet metal integrally with the standard 5, it being first produced inthe form of a tongue projecting from the upper end of the standard 5 andthen curled around in the form of a cylinder, so as to constitute acylindrical support or journal forthe bolt, which latter is in the formof a sleeve 7, rotatably mounted thereon. This sleeve is formed fromvthe blank shown in Fig. 6, which is provided with a V-shaped slot 8,which constitutes a cam when the fiat plate or blank shown in Fig. 1 6is curled around the pintle 6, and with which cam-slot or groove 8engages a pin 9, arranged transversely of the pintle 6 and having itsupper end reduced in diameter, as shown at 10, and riveted in the upperside of the tubular pintle, While its lower end 11 is similarly reducedand riveted in the base-plate 4:, the pin 9 passing throughthe slot 8,where it projects from the under side of the pintle 6, and thus at onceconstituting a support for the pintle and a lug for forcing the sleeve 7back and forth as it is rotated on the pintle. The blank of which thesleeve 6 is formed is formed on one side with a projection 12, whichconstitutes a handle for the operation of the bolt or sleeve 7, and onanother side of this blank, diagonally opposite the projection 12, isformed a projection 13, whose end is turned up in the form of a hook 14and which is adapted to first enter the keeper 3 and then engage withthe outer side thereof as the sleeve rotates, and thus serve to pull therail 2 toward the rail 1, while securely locking the sashes together,

and at the same time to either raise the rail 2 or depress the rail 1,so as to bring the rails into alinement, by virtue of the engagement ofthe projection 13 with the under side of the keeper3, as the sleeve 7 isrotated from left to right and the projection 13 thereby raisedrelatively to the keeper. It will also be seen that the outer edge ofthe keeper is formed with a bevel or cam 15, with which the inner sideof the hook 14 engages as it turns upwardly, and thus better adapts thehook for clamping the sash-rails together. When the bolt is in itslocked position, as

shown in Figs. 4 and 5, the inner end of the cam-slot 8 will havearrived at the pin or lug 9, and in order that the bolt may be heldagainst accidental displacement this inner end of the cam-slot isprovided with a supplemental recess S into which the ing 9 snaps whenthe. bolt reaches its locked position. The keeper 3 is also formed,preferably, of sheet metal, it being constituted of a strip which is cutout on one side at an intermediate point to form the cam 15 and bowedupwardly at this point to permit of the engagement therewith of the hook14, while the ends of the strip are turned outwardly to constitutefootpieces 3* for the attachment thereof to the sash-rail, and hence itwill be seen that if in anyinstance it should be found that the bowedpart of the keeper is too high or too low for the bolt its ends may besqueezed together or spread apart until the desired adjustment isattained, and yet it will possess all necessary strength and rigidityafter it is secured to the sash.

It is of course understood that the cam-slot 8 being V-shaped its effectwill be to first project the bolt through the keeper and then pull it ina direction awayfrom the keeper, so

as to bind the sash-rails together, which may be done veryeffectually,.owing to the great difference in leverage between theprojection 13 and the'handle 12. It will also be seen that the handle 12is so situated with reference to the other end of the blank where it iscurled around the pintle 6 that the locking movement of the handle willbe in a direction toward such end of the blank, and hence will not tendto uncurl the blank or spring it from the pintle.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. In a sash-lock, the combination of a horizontal pintle adapted to besecured to one sash, a keeper adapted to be secured to the other sash, alug projecting transversely of said pintle and a sleeve journaled onsaid pintle and having a cam-slot with which said lug engages and a hookformed on and projecting from the edge of said sleeve at one end forengaging said keeper, substantially as set forth.

2. In a sash-lock the combination of a horizontal pintle adapted to besecured to one sash, a keeper adapted to be secured to the other sash, alug projecting transversely of and supporting said pintle and a sleevejournaled on said pintle and provided in its side with a cam-slot withwhich said lug engages and at its end with a hook for engaging with toone sash, a base=plate adapted to be secured to the other sash, astandard rising from and formed integrally with said base plate, and ahorizontal pintle form ed of sheet metal integrally with said standardand rolled into a cylindrical form, and a bolt journaled on said pintleand adapted to engage said keeper, substantially as set forth.
